Scaling an ec2 instance from r4.large to r4.4xlarge is called vertical scalability.
A system's elasticity is described by its scalability. Although we frequently use it to allude to a system's capacity for growth, it is not just used in this sense. Accordingly, we can scale up, scale down, and scale out. Vertical scaling, also known as scaling up, refers to the addition of more resources to a system in order to fulfill demand. Vertical scaling describes increasing the power of your current machines, and horizontal scaling refers to adding more nodes. For instance, vertical scaling would include updating the CPUs if your server needed additional processing capacity. Additionally, the memory, storage, or network speed can be vertically scaled.
